NewColor Property (GrayScaleToDuotoneCommand)

Example 





Array of Leadtools.RasterColor structures that specifies an array of colors that will be mixed with the original gray values. .NET support WinRT support Silverlight support
Syntax
public RasterColor[] NewColor {get; set;}
'Declaration
 
Public Property NewColor As RasterColor()
'Usage
 
Dim instance As GrayScaleToDuotoneCommand
Dim value() As RasterColor
 
instance.NewColor = value
 
value = instance.NewColor
public RasterColor[] NewColor {get; set;}
 get_NewColor();
set_NewColor(value);
public:
property array<RasterColor>^ NewColor {
   array<RasterColor>^ get();
   void set (    array<RasterColor>^ value);
}

Property Value

Array of Leadtools.RasterColor structures that specifies an array of colors that will be mixed with the original gray values. If this parameter is set to null, the Color property must contain a valid color. Pass null when you want the command to create the array of colors, two colors when replacing both colors in a binary image, or 256 colors when using a custom array of colors.
